What happens is this simple: after a few minutes, about 6 or so, the entire content of the screen stays still. In some minor situations only the applications panel of KDE Plasma.
If music is playing it continues playing, so only graphics are hung. Yet in most cases the power button won't shut down the computer, as it usually does.
At least this is the case using kwin on x11, and not on wayland. It only happens on "radeon" and not on Intel or "radeonhd".
Correct, but a TV is intended for videos only. That's why it
implements only the lower HDMI standard.
Interlaced transmits only halve the lines with each frame, so a 60Hz
mode effectively either becomes a 30Hz mode, halving the vertical
resolution or adaptive motion compensated which the know visual
artifacts. Depending on what the deinterlacing setting on your TV
is.
You could just add a progressive 1920x540@60 or 1920x1080@30 mode
manually and would have the same effect with probably better
quality. See https://de.wikipedia.org/wiki/Deinterlacing for
reference.
If you can give us some more information what is happening when the
system freeze we could try to narrow this down, but we can't spend
much time on a very specific use case in a driver which is in
maintenance mode.

24fps is intended for video only. Anything interactive at
24fps, as just moving the mouse around, is extremely choppy.
No way anyone would prefer that over an interlaced
resolution or a lower resolution. That is, by far, the worst
option.
Just try it on your screen, set it to 24Hz or alike, and
tell me your experience. You can't even tell where the mouse
is going to go.
Interlaced resolutions are not used
any more on modern hardware, so they
are not well tested.
